Ok, unregistered, uninstalled the dongle emulator, plugged in the real dongle and re-registered. Got back on fine but still no tournaments showing for me.
It looks like my leaderboards and unlocked items are still intact but it shows that I haven't played any courses or got any scores on any of the holes and so I don't have any player stats anymore.
Oh well, they weren't that impressive anyway.
My new cabinet # is: 30036
